Bug#822523: xorg: Xorg -configure fails: "Number of created screens does not match number of detected devices."
I played around with this issue a little bit more. This is what I learned: I booted from a fresh drive I installed Debian Testing on and it does not seem to be affected by this issue. That's notable. I was not able to revert to EXA on the ZBox/Radeon HD 8250 system. The xorg log says that mode is not supported on this hardware. I also tried enabling glamor on the NVida GTX 970 and that failed, saying something like "glamor initialization failed" in the log. I didn't think glamor was supported there anyway, so I'm not surprised. I moved this installation to a system which has an Radeon HD 5770 in it and I am not seeing any similar issues here. Finally, I probably won't be able to test this again in the future as I am planning on putting that ZBox to use and won't have access to it for awhile.

The advice on the wiki link above is non-helpful. So, what now? Yes, Xorg -configure is known broken. Don't use that. Just write Section "Device" Identifier "glamor" Option "AccelMethod" "glamor" EndSection to /etc/X11/xorg.conf.
